三轴式变速器的传递路线三轴式变速器的传递路线 Transmission mechanism of two or three shaft type speed variatorThree shaft transmission for rear wheel drive front engine car. The following to the transmission of Dongfeng EQ1092 truck as an example, the structure diagram as shown in Figure 3 - 18 shows, there are three main transmission shaft, a shaft, a two shaft and intermediate shaft, so called the three shaft transmission. In addition to reverse shaft.Three shaft transmission Figure 3 - 18 Dongfeng EQ1092 truckL - axis 2 - shaft constant mesh gear 3 - shaft constant mesh gear engagement ring gear 4, 9 - joint sleeve; 5 - four gear jointing gear ring 6 - two axis and four gear 7 - two axis third gear 8 - third gear engagement ring gear 10 - second gear engagement ring gear 11 - two 12 - two stall gear shaft, a reverse gear sliding gear 13 straight tooth transmission housing 14 - two 15 - axis intermediate shaft reverse gear shaft 16 - 17, 19 - reverse idler gear 18 intermediate shaft, reverse gear 20 the intermediate shaft intermediate gear shaft gear box 21 - 22 - four 23 - intermediate shaft gear shaft constant mesh gear 25 - 24, 26 - splined hub shaft bearing cover 27 oil return threadsThe transmission is a five speed transmission, the gear transmission: (1) the gapTwo axis of each joint sleeve, drive gears are in the position of idling intermediate, the power is not transmitted to the second axis. (2) aForward a reverse straight tooth sliding gear 12 and a 18 intermediate shaft gear meshing. Power through a shaft gear 2, intermediate shaft constant mesh gear 23, intermediate shaft gear, a reverse gear shaft 18 two 12, to second axis which rotate clockwise (with the first axis of same direction). (3) gearAfter the shift joint sleeve 9 and the two shaft intermediate gear 11 engages the 10 engagement ring gear. Power by 2, 23, 20 gear, 11, 10, 9, 24, to the two shaft so that the clockwise rotation. (4) gearForward engagement sleeve 9 and the two shaft gear box 7 engagement ring gear 8 engages. Power by 2, 23, 21 gear, 7, 8, 9, 24, to the two shaft so that the clockwise rotation. (5) four fileAfter the shift joint sleeve 4 and two axis and four gear engagement ring gear 5 engages 6. Power by 2, 23, 22 gear, 6, 5, 4, 25 connected to the two shaft, the clockwise rotation.Five (6)Forward clutch engagement ring gear 2 and a 4 shaft constant mesh gear 3 engages. Power directly by a shaft, 2, 3, 4, 25, to the two shaft, transmission ratio is 1. Because of the two shaft speed is same with a shaft gear, so called direct file. (7) reverseAfter the shift, reverse gear shaft on the two straight tooth sliding gear 12 and 17 engaged reverse gear. Power by 2, 23, 18 gear, 19, 17, 12, pass two axis the counterclockwise rotation, backward moving car. Comparison of the transmission line and the other gear, due to multiple transmission reverse idler gear, so to change the direction of rotation of the two shaft.
